uhhh.....the Blackfly was first. My stove is black. The Iso has those 4 screws with a double wick coming out of them and the pot stand. Mine has just the single looping wick.
But...whatever the name, it was the very first wick stove Tinny built. The windscreen was crucial in keeping the temp of the stove cool enough as to not overheat. I finally knew how to work with it. It's a great little stove if you want to slow-cook, which sometimes I enjoy. I did find it difficult to pour the alcohol back without water from the jacket getting in the way. After awhile of using the thing, I knew pretty much how much alchy I needed for certain meals or tea. Like anything else, one gets familiar with their gear and its personality. : )
Also...fuel usage went a very long way. That's one of the great things about his wick stoves. It will boil, and you can set up your campsite while it's heating. I just found that my style of camping turned out not what I thought it would be.
